Question

我正在尝试实现类似这种地图的功能：http://www.geocodezip.com/SO_OverQueryLimitC.html

但是，我没有设法在其上显示InfoWindow。我想向InfoWindow显示具有多个确切位置的数据。

这是我的代码：

HTML：

<section id="GoogleMaps" ng-controller="MapsController">
  <div class="container">
    <div>
       <div id="map_canvas"></div>
    </div>
  </div>
</section>

控制器：

.controller('MapsController', ['$scope', '$http', function ($scope, $http) {
$scope.loadData = function () {
 var url = 'data/LatLng.json';
 return $http.get(url).then(function (response) {
     return response.data;
 });
};


$scope.initMap = function (data) {
 var mapOptions = {
     zoom: 7,
     center: new google.maps.LatLng(3.9443, 101.6954),
     mapTypeId: google.maps.MapTypeId.ROADMAP
 }
 var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
 var infowindow = new google.maps.InfoWindow();

 var markers = [];
 var LatLng;
 var text;
 var marker;
 data.forEach(function (item) {

     var icons;
     LatLng = new google.maps.LatLng(item.LAT, item.LON);
     text = item.TYPE1;

     if (item.TYPE1 == '1' && item.TYPE2 == '1') {
         icons = 'http://www.googlemapsmarkers.com/v1/' + '1' + '/FD7567';
     }
     else if (item.TYPE1 == '1' && item.TYPE2 == '2') {
         icons = 'http://www.googlemapsmarkers.com/v1/' + '2' + '/FD7567';
     }
     else if (item.TYPE1 == '1' && item.TYPE2 == '3') {
         icons = 'http://www.googlemapsmarkers.com/v1/' + '3' + '/FD7567';
     }
     else if (item.TYPE1 == '2' && item.TYPE2 == '1') {
         icons = 'http://www.googlemapsmarkers.com/v1/' + '1' + '/6991FD';
     }
     else if (item.TYPE1 == '2' && item.TYPE2 == '2') {
         icons = 'http://www.googlemapsmarkers.com/v1/' + '2' + '/6991FD';
     }
     else {
         icons = 'http://www.googlemapsmarkers.com/v1/' + '3' + '/6991FD';
     }

     marker = new google.maps.Marker({
         position: LatLng,
         icon: icons,
         clickable: true,
     });

     markers.push(marker);
 });

 var options = {
     imagePath: 'images/m'
 };

 var markerCluster = new MarkerClusterer(map, markers, options);

 ///get array of markers currently in cluster
 var allMarkers = markerCluster.getMarkers();

 //check to see if any of the existing markers match the latlng of the new marker
 if (allMarkers.length != 0) {
     for (var i = 0; i < allMarkers.length; i++) {
         var existingMarker = allMarkers[i];
         var pos = existingMarker.getPosition();

         if (LatLng.equals(pos)) {

             text = text + " & " + text;
         }
     }
 }

 google.maps.event.addListener(marker, 'click', function () {
     console.log('hi'); //return nothing
     infowindow.close();
     infowindow.setContent(text);
     infowindow.open(map, marker);
 });

 markerCluster.addMarker(marker);
 return marker;

 };


 $scope.loadData()
 .then($scope.initMap);

 }])

脚本：

addTag('script', { src: 'http://maps.googleapis.com/maps/api/js' }, sync);
addTag('script', { src: 'assets/js/markerclusterer.js' }, sync);

更新：我尝试在click事件中添加console.log（），但它什么也没显示。当我点击它时，它没有进入该功能。

任何想法如何解决？

谢谢。

Answer 1

为了在点击MarkerClusterer后显示信息窗口，需要应用以下更改：

1）将zoomOnClick设置为false以禁用默认点击处理程序：

var options = {
 zoomOnClick: false
};

2）为click对象注册自定义 MarkerClusterer事件处理程序：

 google.maps.event.addListener(markerCluster, "click", function (mCluster) {
     infowindow.setContent("<h2>Some content goes here...</h2>");
     infowindow.setPosition(mCluster.getCenter());
     infowindow.open(map);
 });
